Hello everyone,
I would like to ask your help for an issue we have here.
We have a robot with a C2 controller. The robot is operating for many years now with no problems and is controlled by an Allen Bradley PLC connected with DeviceNet.
Last week we had a scheduled power outage. The robot was properly shut down and the only thing I did was to replace the CMOS battery because it time.
When power was restored the system started well but '6503 Configuration Error I/O DN2DRV' appears in the alarm list and communication with the PLC is down.
Power on DeviceNet is ok (24VDC) and also they are CAN+ and Can- both showing 2VDC and there's a chance the PLC is to blame (I already checked and everything seems OK).
In the meantime I'm going deeper into all manuals and documentation by myself, is anybody of you that has already seen a similar behaviour?
Any good suggestion?
Thanks in advance,
Vinz
